NEW YORK (AP) French Open runner-up Marketa Vondrousova has pulled out of the U.S. Open because of an injured left wrist.

The 20-year-old lefty from the Czech Republic hasn't played a match on tour since bowing out of Wimbledon in the first round in July.

Vondrousova had been seeded No. 17 in the women's draw at Flushing Meadows, where play begins Monday.

The U.S. Tennis Association announced Vondrousova's withdrawal Friday and said Zhang Shuai - the next player eligible to be seeded - will move into her line in the tournament bracket. Zhang's line will be filled by a qualifier or lucky loser.

Vondrousova reached the U.S. Open's fourth round last year, her best showing at a Grand Slam tournament until her run to the final at Roland Garros in June.
